找不到用于处理Intent的活动{act = android.intent.action.DIAL} [英] No Activity found to handle Intent { act=android.intent.action.DIAL }

问题描述

我想打开电话拨号器.但是显示错误.我已经在Android Manifest上声明了CALL_PHONE的权限，并且还在Android Manifest中声明了类.

I want to open my phone dialer .But it shows error. I have declared permissions for CALL_PHONE on Android Manifest and also declared class in Android Manifest.

case R.id.action_call:
Log.d("Action_call","INside Action call");
Intent dialer = new Intent(Intent.ACTION_DIAL);
startActivity(dialer);
return true;

推荐答案

对于 ACTION_DIAL Intent，您不需要任何权限.因此，请从 AndroidManifest.xml 中删除 CALL_PHONE 权限.

You don't need any permissions for ACTION_DIAL Intent. So remove CALL_PHONE permission from AndroidManifest.xml.

您尚未传递任何号码来触发Intent.

You have not pass any number to fire dial Intent.

使用 tel:，后接电话号码作为传递给Uri.parse()的值:

Use tel: followed by the phone number as the value passed to Uri.parse():

尝试此代码.

 String number = "1234567890";
 Uri number = Uri.parse("tel:" + number);
 Intent dial = new Intent(Intent.ACTION_DIAL);
 dial.setData(number);
 startActivity(dial);

您可以先检查设备上是否支持电话

You can first check whether telephony is supported on device

private boolean isTelephonyEnabled(){
    TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
    return tm != null && tm.getSimState()==TelephonyManager.SIM_STATE_READY
}
